To make seed raising mix, combine coco coir or peat moss, vermiculite or perlite, river sand, worm castings (or compost), following the proportions outlined below.
Here's a simple recipe for creating your own seed raising mix:
Ingredients:
- 2 parts coco coir or peat moss
- 1 part vermiculite or perlite (or a combination of both)
- 1 part river sand
- ½ part worm castings
- ½ part finely sifted compost
Instructions:
- Gather your ingredients: Ensure you have all the necessary components ready.
- Combine the ingredients: In a large container, thoroughly mix together the coco coir or peat moss, vermiculite or perlite, and river sand.
- Add the worm castings and compost: Incorporate the worm castings and finely sifted compost into the mixture. If you cannot find worm castings, double the amount of compost.
- Mix well: Ensure all the ingredients are evenly distributed throughout the mix.
- Moisten lightly: Lightly dampen the mix with water, ensuring it is moist but not soggy.
Ingredient Breakdown and Purpose:
Ingredient | Purpose | Alternatives |
---|---|---|
Coco Coir/Peat Moss | Provides moisture retention and aeration. | Sphagnum peat moss |
Vermiculite/Perlite | Improves drainage and aeration. | Horticultural sand |
River Sand | Enhances drainage and provides weight to anchor seedlings. | Coarse sand (ensure it's washed to remove salts) |
Worm Castings/Compost | Provides nutrients to seedlings. | Well-rotted manure (use sparingly) |
Tips for Success:
- Sifting: Sifting your compost helps remove large chunks that can hinder seedling growth.
- Moisture: The seed raising mix should be moist but not waterlogged.
- Storage: Store unused mix in an airtight container.
- Sterilization (optional): If you're concerned about damping-off, you can sterilize the mix by baking it in the oven at 180°F (82°C) for 30 minutes. Let it cool completely before using.
By following these simple steps, you can create a seed raising mix that will provide your seedlings with the perfect environment to thrive.
